[0001] The present invention relates to the technical field of corrugated pipe processing, in particular to double-wall corrugated pipe connection part shaping equipment and a shaping method thereof. Background Art

[0002] Bellows are elastic elements and pressure-bearing elements, mostly used to compensate for the expansion and contraction displacement of pipelines. After the bellows are formed, due to elastic rebound, the wave pitch and waveform of the bellows are different from the design requirements, and shaping operations must be performed.

An inner groove that matches the surface of the corrugated pipe is provided on the surface of the regularization wheel. Two regularization wheels are provided, and heating and cooling are respectively provided by temperature control equipment to heat and cool the two regularization wheels respectively. The upper regularization wheel is used to heat and extrude at the same time, and the material is softened by the heat and then regularized, which is more convenient for shaping. After being softened by the heat, the lower regularization wheel is used to cool while extruding, so that the material can be quickly cooled and formed to complete the regularization. The corrugated pipe is transported to the support rod through the auxiliary loading platform for loading, and then the support rod is driven to rotate by the rotating seat to perform regularization and unloading in sequence, and then the processing is cyclically carried out.
